Bookmate Data Breach

What happened

In mid-2018, the social ebook subscription service Bookmate was among a raft of sites that were breached and their data then sold in early-2019. The data included almost 4 million unique email addresses alongside names, genders, dates of birth and passwords stored as salted SHA-512 hashes.

Exposed data

Recommended actions

• Change your Bookmate password immediately, and update it anywhere you reused the same password.
• Enable two-factor authentication on the affected account and on your critical services (email, banking).
• Watch for targeted phishing emails referencing Bookmate — attackers weaponise breach data quickly.
• Exposed identity data raises identity-theft risk — consider credit monitoring or a credit freeze.
• Check whether your email address appears in this breach on haveibeenpwned.com.
